About Domain IDs

The configured domain ID can be preferred or static. By default, the configured domain ID is 0 (zero) and
the configured type is preferred.
The 0 (zero) value can be configured only if you use the preferred option.
Note
If you do not configure a domain ID, the local switch sends a random ID in its request. We recommend that
you use static domain IDs.
When a subordinate switch requests a domain, the following process takes place (see the figure below):
• The local switch sends a configured domain ID request to the principal switch.
